BPR Curvatrici DP7 is the integrated digital display and operator interface used on the company’s tube‑bending machines. Common failure modes reported for this unit include loss of visual output (screen blank or flickering), backlight degradation, and intermittent touch or button response due to capacitor aging or solder joint fatigue. The control board often shares components with other BPR series displays, so a faulty power regulator or damaged LCD driver IC can propagate across the panel. First‑check steps: verify 12 V/24 V supply rails at the DP7 connector; inspect for burnt or swollen capacitors on the display PCB; and review any error codes logged in the machine’s main controller that reference “DP7” or “display failure.”[oss-gpt-20b]
